# Couple of functions that transform a given integer into a mixed-base string
# representation and back. The string representation is formed by three 'A-Z'
# characters (base 26), followed by four '0-9' digits (base 10).

# Some examples:
# | Integer | Pattern |
# |       0 | AAA0000 |
# |       1 | AAA0001 |
# |    9999 | AAA9999 |
# |   10000 | AAB0000 |
